Choosing a flowmeter that creates low permanent pressure loss is most important in Compressors & Blowers requirements can reduce energy loss, increase efficiency & saves money. Airflow rate measurement & control is utmost in the textile, automobile, steel and power, chemical & pharmaceuticals process. Selecting an appropriate flow measurement technique can be a daunting task. If we are aware of technologies that are suitable for a particular application, minimizing energy costs can help narrow the choice. Pressure drop loss is a major concern as example Orifice flow meter has approx 2psi -3psi pressure loss which is equal to 1-1.5% energy loss. LEOMI thermal mass (calorimetric) flow meters work on the physical principle of thermal dispersion from a heated element to the ambient medium (e.g. air or gases). And it is the proven technology that provides great savings in energy costs by almost No permanent pressure loss & high turndown ratio to the plant operators hence

APPLICATION Aeration air flow rate monitoring for control of Dissolved Oxygen levels in Effluent primary treatment plant. CUSTOMER India’s biggest Pharmaceutical drugs manufacturing group, Gujarat. PROBLEM An Integrated pharmaceutical plant with various departments such as API bulk drugs, tablets, liquid syrup manufacturing facility has a variable load of effluent water with a wide range of toxic organic and inorganic effluent into the effluent treatment plant for processing.  This poses a challenge to maintain DO levels with respect to aeration air injection for BOD,COD & TOC control as per regulatory norms for resuage. Air Blowers are operated on a fixed pressure control loop which creates a problem on inefficient DO controls. DO is a function of air flow not pressure.  Efficient Dissolved Oxygen ( DO) control is a challenge to obtain without accurate aeration air flow metering. Ineffective DO control means loss of energy and insufficient bacterial growth for optimum BOD levels.

  Thermal mass flow meters can be used in beverage production and chilling applications to measure the flow rate of fluids such as water, juice, and other beverages. In these applications, the flow meter is typically installed in a pipe or tube that carries the fluid. There are several benefits to using a thermal mass flow meter in beverage production and chilling applications: Accuracy:  Thermal mass flow meters are known for their high accuracy, which is important for accurately measuring the flow rate of fluids in a beverage production process. Low-pressure drop:  Thermal mass flow meters have a low-pressure drop, which can be important in applications where the pressure of the fluid is a concern. Versatility:  Thermal mass flow meters can be used to measure a wide range of fluids, including water, juices, and other beverages. No moving parts:  Thermal mass flow meters do not have any moving parts, which makes them low maintenance and less prone to wear and tear. Good repeatability:
